Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500°C, and 80 m/s and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 13 kg/s. The properties of the steam are = 0.086442 m³/kg, h=3446 kJ/kg, and 2 = 2437.7 kJ/kg. P₁-4 MPa T₁ - 500°'℃ V₁-80 m's P₂ - 30 kPa 32-0.92 Vyu 30 m/s Determine the change in kinetic energy.
